Lagrangian points:
- L1: Magshield
- L3: The Hidden Node
- L4: Meng node
- L5: Zhang node
Mostly Sophic League (including Penglai), with some Zoefic, Solarist, Fomac, and Metasoft presence in orbit. The planetary atmosphere deep below the top clouds has an extensive ecosystem, where many of its creatures host descendants of Advection of Pure Drylines. The Meng node is aligned with the Fomalhaut Acquisition Society, while the Zhang node is largely independent. Curiously, the L3 node is occupied by a single mysterious structure known as the Hidden Structure, which appears to be occupied by an S2 uncommunicative transapient. Surrounding it is a dense restriction swarm.

Zhuque (The Red Bird of the South)

Lagrangian points:
- L4: Ling node
- L5: Guang node
Cosmopolitan, with almost all empires and many major Houses and groups like the Mirrored Owls, but the Keter Dominion and the Sophic League attracted a large number of the polities around this planet. Fangzhang is mainly Federationist, while Yingzhou is home to several polities aligned with the Silicon Generation and others independent. Since the 7000s, the Sophic League, Metasoft, and the Utopia Sphere had been dominating both Ling and Guang nodes, but for the last thousand years, the Stella Umma from the nearby Jinvanco system had been carving its presence here as well.

Baihu (The White Tiger of the West)

Mainly Zoefic and Sophic, with a large unaligned fraction. The planetary atmosphere is home to many groups, including the Mirrored Owls. Daiyu is split between dozens of marine nations with diverse alignments. Many Great Houses, including the Genens, have representatives in the Jian node, as well as the Cyberians and the MPA, while the Bing node is aligned with both the TRHN and the Keter Dominion.
